Dab tsi yog qhov txawv ntawm LED High-power thiab me zog?

Lub zog ib leeg ntawm high-power LED teeb yog siab dua, qhov ci ci dua, thiab tus nqi siab dua. Qhov ntsuas tam sim no ntawm lub zog me me LED teeb yog 20mA, thiab cov ntsuas tam sim no tuaj yeem suav tias yog lub zog siab nrog cov ntsuas tam sim no siab dua 20mA. Lub zog hluav taws xob dav dav yog: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, thiab lwm yam. Lub teeb ci tseem ceeb yog LM (lumen), thiab qhov ci ci ntawm lub zog me me feem ntau yog MCD. Ob chav no hloov tsis tau. Tam sim no, raws li ib tug tshwm sim ntsuab, ib puag ncig tiv thaiv, lub zog-txuag lub teeb qhov chaw yog dav siv nyob rau hauv tsheb teeb, teeb nyem, teeb thiab lwm qhov chaw. Yog vim li cas vim li cas high-power LED teeb yog hu ua qhov no tsuas yog rau me me-power LED teeb. Muaj peb hom kev faib tawm: thawj qhov yuav tsum tau muab faib ua 0.5W, 1W, 3W, 5W, 10W. .100W yog txawv, raws li tag nrho lub zog ntawm cov khoom molding tom qab ntim. Qhov thib ob hom tuaj yeem muab faib ua: loj-sized epoxy resin ntim, xyaum mermaid epoxy resin ntim, txhuas ntim, txhuas, txhuas, thiab txhuas. Peb hom substrate (MCPCB) encapsulation, Rau ntim, hwj chim -type SMD pob, MCPCB integrated pob, thiab lwm yam. Hom thib peb tuaj yeem muab faib ua cov khoom siv hluav taws xob qis qis thiab cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob raws li nws qib ntawm lub teeb aging. Tau kawg, vim tias muaj ntau qhov tsis sib xws ntawm high-power LED teeb nws tus kheej, yuav muaj cov qauv kev faib tawm sib txawv raws li qhov sib txawv. High-power LED teeb tseem yog ib qho ntawm cov khoom ntim LED, uas yog qhov tseem ceeb tshaj plaws ntawm semiconductor teeb pom kev zoo rau thaj chaw teeb pom kev zoo. Thaum siv high-power LED teeb, koj yuav tsum nkag siab txog lub teeb faib ntawm lub teeb faib, xim kub faib, thermal kuj thiab xim rendering kom paub lub teeb - siv zog faib daim ntawv qhia ntawm W -class high-power LED teeb. Nws yog ib qho tsim nyog yuav tsum tau siv lub siab-power LED teeb. Cov neeg tsim khoom yuav tsum muab cov neeg siv khoom nrog ntau qhov ntsuas ntsuas ntawm cov khoom siv LED txawm tias cov xim kub ntawm cov teeb pom kev zoo ntawm lub zog LED yog sib npaug, uas yuav cuam tshuam ncaj qha rau cov teeb pom kev zoo; thiab xim kub thiab xim rendering Performance index yog interconnected, thiab qhov kev hloov ntawm cov xim kub yuav ua rau cov kev hloov ntawm cov xim rendering Performance index. Lub thermal tsis kam ntawm high-power LED teeb ncaj qha cuam tshuam rau lub tshav kub dissipation ntawm LED li. Tsawg thermal tsis kam, qhov zoo dua cov cua kub dissipation; lub tshav kub kuj tsis zoo, yog li ntawd qhov kub ntawm lub cuab yeej yuav nce, uas yuav cuam tshuam rau lub wavelength drift ntawm lub teeb. Raws li kev paub dhau los, qhov kub thiab txias nce ib zaug, thiab lub teeb yoj ntev yuav tsum ntws los ntawm 0.2 0.3nm, uas yuav cuam tshuam ncaj qha rau lub teeb pom kev zoo ntawm lub cuab yeej. Kev kub siab dhau los kuj tseem cuam tshuam ncaj qha rau kev pab cuam lub neej ntawm W -theem high -power LED zog -txuag teeb. Xim yog ib qho tseem ceeb qhia ntawm lub teeb dawb LED. Cov xim ntawm lub teeb dawb LED rau teeb pom kev zoo yuav tsum siab dua 80 lossis ntau dua.
